Verdict: Wasabi and apple ganache

It was absolutely horrible! But I should also rather hastily add that I don't think this is a flaw of the recipe, but letting the chocolate seize absolutely ruined any chance of it being nice. The texture was a really nasty grainy, vile mess. So this was entirely my fault for being careless - I've not done any chocolate work in quite a while and completely forgot how fickle it can be. The flavour was actually really interesting though - it seemed to be nicely balanced and really quite complex - so I think this recipe has some great potential, if you're not a muppet. I'll try it again soon (hopefully) and try to be a bit less stupid... so we'll reserve judgement until then!
